6.5L Serpentine Belt Conversion

[ICT_HMMWV]

I have an '89 M998 w/ a 6.5L N/A engine/ 3sp tranny. The engine currently has dual v-belts. The simple question is can I convert the v-belts to serpentine? The more complicated question if possible how?

I believe at minimum you have to swap to a different water pump as it is reversed direction on the serpentine from the V-belt style.
Some of the other accessories may also be reverse spin.

So yes, it is possible, but does involve more than just swapping pulleys.

Water pump backing plate, too.
Different fan since it will spin the other way.

You will need a 200 amp alt also...along with brackets, pullies,
I have most metal parts available for early surp system.

Simpler question is why do you need to? I believe NASCAR still uses v-drive and It’s less likely to slip. I think if it came with serpentine belt great and if not cost doesn’t justify the gains. All you get is it’s easier to adjust belt? What are you looking for end result?

While the cost and effort my not be worth the gain I have never heard anyone assert that a V belt was less likely to slip! mine squeal like a pig stuck under a rail fence every time the fan kicks in. also there is no "adjustment" on a serpentine belt

That’s awesome! It’s classic it’s a quirk of your vehicle nothing wrong with a pig stuck in a fence squeeling I think that’s how I met my first wife . I can’t find my glasses this morning so I’m not really sure what in typing

Serp setup is cleaner, less maintenance, easy for belt changes, I’ve converted many V-belts to Serpentine.
